BACKGROUND
Homeowners may ventilate their homes to increase air flow through the home, cool the home, experience outdoor sounds or scents, eliminate indoor pollutants, smells, or humidity, or to prevent fungosity. Generally, a homeowner may choose to open a fenestration unit to achieve venting. However, opening fenestration units can result in exterior elements, bugs, or allergens entering the home, a decrease in home security, and other unwanted results.

It should also be noted that the accompanying drawing figures referred to herein are not necessarily drawn to scale but may be exaggerated to illustrate various aspects of the present disclosure, and in that regard, the drawing figures should not be construed as limiting.
FIG. 1 is a front view of a venting unit 10 as viewed from an exterior side 6 of a building structure 2, in accordance with some embodiments. As shown, the venting unit 10 may be installed within a wall 4 of the building structure 2, including a sealant 8 and fasteners (not shown) for securing the venting unit 10 in place. The sealant 8 may also act as an air-tight seal between the wall 4 and the venting unit 10.
Further referring to FIG. 1, the venting unit 10 is shown as would be viewed from an exterior side 6 of the building structure 2, where the exterior building side 6 is exposed to the outdoor elements. The venting unit 10 defines an exterior venting side 9 and an interior venting side 7 (e.g., as shown in FIGS. 3A-3B), where the exterior venting side 9 is exposed to the outdoor elements and the interior venting side 7 is exposed to an interior building side 5. The venting unit 10 includes a frame 12 (e.g., as shown in FIGS. 3A-3B) which includes a plurality of frame members. The plurality of frame members may include an upper frame member 14, a lower frame member 16, a first side frame member 18, and a second side frame member 20. The frame 12 may be configured to be installed within the wall 4 of building structure 2. The frame 12 defines an airway 44 (e.g., as shown in FIGS. 4A-4B) for air to pass from the exterior venting side 7 of venting unit 10 to an interior venting side 7 of the venting unit 10 (shown in FIG. 3A-3B). A rectangular configuration of the venting unit 10 in is shown and described by way of example, however other configurations (e.g., square, curved, and so forth) are also contemplated.
Although the venting unit 10 may be installed directly into the wall 4 of the building structure 2 as shown in FIG. 1, the venting unit 10 may also be maintained within, or coupled to, a fenestration unit 30. FIG. 2 is a front view of the venting unit 10 maintained within a fenestration unit 30 as viewed from the exterior building side 6 of the building structure 2, in accordance with some embodiments. The fenestration unit 30 may include a frame assembly 32 which includes a plurality of frame assembly members. The plurality of frame assembly members may include an upper frame assembly member 34 (e.g., a head), a lower frame assembly member 36 (e.g., sill), a first side frame assembly member 38 (e.g., a first jamb), and a second side frame assembly member 40 (e.g., a second jamb). The venting unit 10 may be coupled to any one or more of the frame assembly members. The frame assembly 32 can also be configured to maintain one or more glazing panels or other panels, which may include sheets of glass, in addition to the venting unit 10.
In some embodiments, as shown in FIG. 2, the venting unit 10 is coupled to the lower frame assembly member 36. In other embodiments, the venting unit 10 is coupled to the upper frame assembly member 34. In still other embodiments, the venting unit 10 may be coupled to both the first side frame assembly member 38 and the second side frame assembly member 40. Though a four-sided configuration of the fenestration 30 is shown and described by way of example, other configurations (e.g., three-sided, five-sided, six-sided, curve top, circle-head, and so forth) are contemplated. The venting unit 10 may be a complementary shape to the fenestration unit 30 (e.g., the rectangular venting unit 10 and the four-sided fenestration unit 30), but other configurations are also contemplated. Though not shown, venting unit 10 may be coupled to a fixed panel, or essentially replace the fixed panel, of a sliding fenestration unit, such as a sliding patio door.
FIG. 3A is an isometric view of the venting unit 10 of FIGS. 1 and 2, in accordance with some embodiments. The venting unit 10 defines the exterior venting side 9, which is exposed to the outdoor elements. The venting unit 10 includes a platen 50 that may be positioned toward the exterior venting side 9 of the venting unit 10 or may define a portion of the exterior venting side 9. The venting unit 10 is configured to be installed with the exterior building side 6 facing outwardly relative to the interior of the building structure 2. The venting unit 10 defines the interior venting side 7, which is not exposed to the outdoor elements. The venting unit 10 includes an inner panel 80 (e.g., as shown in FIG. 3B) that may be positioned toward the interior venting side 7 of the venting unit 10 or may define a portion of the interior venting side 7.
Further to FIG. 3A, the platen 50 is operable to cover an airway 44 (e.g., as shown in FIGS. 4B-4C). The venting unit 10 includes the frame 12 that defines the airway 44. The airway 44 is configured to allow air to enter the airway generally from the platen 50 and flow through the airway 44 from the outer platen 60 to the inner panel 80 (e.g., as shown in FIGS. 4A-4C). The platen 50 is shown in a closed position in FIG. 3A such that the airway 44 covered and air is not able to pass through the airway 44. The platen 50 may further include a weather seal 42 (e.g., as shown in FIG. 4C) defined around a perimeter of the platen 50 and a perimeter of frame 12.
FIG. 3B is an isometric view of the venting unit 10 of FIG. 3A, in accordance with some embodiments. The venting unit 10 may include an inner panel 80, which is configured to allow the air passing through the airway 44 (e.g., as shown in FIGS. 4A-4C) to enter the building structure 2 (e.g., enter the interior of a home). The inner panel 80 may include a screen 82. The air moves through the airway 44 in an airflow direction 46, through the venting unit 10. The venting unit 10 may also include an actuator system 90. The actuator system 90 may be coupled to the platen 50 and the frame 12 and may extend through the frame 12 (e.g., as shown in FIGS. 4A-4B). The actuator system 90 may include a plurality of actuators 91. One actuator 92 of the plurality of actuators 91 may be located in each corner of the venting unit 10, as shown in FIG. 3B, or otherwise positioned at various locations that facilitate selective opening (e.g., at various angles) of the venting unit 10. However, each actuator 92 in the plurality of actuators 91 may be located at any location about the frame 12, depending on the application. The actuator system 90 will be subsequently described in more detail.
FIGS. 4A and 4B is an isometric view and a top view, respectively, of the venting unit 10 with the frame 12 and the weather seal 42 removed, in accordance with some embodiments.
In some embodiments, as shown in FIGS. 4A-4B, the venting unit 10 may include an outer panel 60. The outer panel 60 may be generally located closer to the platen 50 to receive airflow from the platen 50. In some embodiments, the outer panel 60 may include, but is not limited to, a louvered panel (shown in FIGS. 9A-9B).
As shown in FIG. 4B, the venting unit 10 may include a filter 70 arranged to filter air passing through the airway 44. The filter 70 may be generally arranged closer to the inner panel 80 of the venting unit 10 such that filtered air flows out of the inner panel 80 of the venting unit 10 and into the building structure 2. In some examples, the filter 70 includes, but is not limited to, a high efficiency particulate air (HEPA) filter.
In some embodiments, the venting unit 10 defines a passive ventilation system. The passive ventilation system may use natural ventilation (e.g., cross ventilation and/or stack ventilation), which will be subsequently described in more detail. In this embodiment, the air is pulled through the airway 44 by the movement of the platen between a closed position (e.g., as shown in FIGS. 3A-3B) and an open position (e.g., as shown in FIGS. 5A-7B) without mechanical assistance (e.g., a fan), which will be subsequently described in more detail. The platen 50 is operable to cover the airway 44, where the airway 44 is defined by the frame 12. The airway 44 may be defined though the outer panel 60, the filter 70, and the inner panel 80. In some embodiments, the venting unit 10 may be used in tandem with other ventilation systems of the building structure, which will be subsequently described in more detail.
In other embodiments, the venting unit 10 may define a mechanical ventilation system. In such embodiments, the venting unit 10 may further include a fan 74, or a plurality of fans 74, adjacent the filter 70 (e.g., as shown in FIG. 8B). The fan 74 may include, but is not limited to, a propfan. The fan 74 may drive air through the airway 44 along the airflow direction 46. In some embodiments, the fan 74 may be adjacent the outer panel 60 and the filter 70 and positioned therebetween. In other embodiments, the fan 74 may be located within the frame 12.
In still further embodiments, the venting unit 10 may define a hybrid ventilation system. The hybrid ventilation system may use a combination of both natural ventilation (e.g., cross ventilation and/or stack ventilation) and mechanical ventilation (e.g., the fan 74 of FIG. 8B). The venting unit 10 may include a sensor to measure flow rate of air through the airway 4. If the sensor measures that a flow rate of air is too low with natural ventilation, the fan 74 may be turned on to increase the flow rate of the air through the airway 44. Similarly, the venting unit 10 may include a switch that allows a user to turn the fan 74 on and off such that the venting unit 10 is transitioned between natural ventilation and mechanical ventilation.
As shown in FIGS. 4A-4B, the venting unit 10 is arranged such that the outer panel 60 is adjacent to the platen 50 and the filter 70 and is positioned therebetween, the filter 70 is adjacent the outer panel 60 and the inner panel 80 and is positioned therebetween. However, other arrangements are contemplated, such as, for example, reversing the positions of the filter 70 and the outer panel 60.
In some embodiments, as shown in FIGS. 4A-4B, the venting unit 10 further includes an actuator system 90. The actuator system 90 may be coupled to the platen 50 and the frame 12 and may extend through the frame 12. The actuator system 90 may include a plurality of actuators 91. At least one actuator 92 of the plurality of actuators 91 may be located in each of the four corners of the venting unit 10. The actuator system 90 can include more than four actuators or fewer than four actuators, depending on the application. Further, the location of each actuator 92 in the plurality of actuators 91 is not limited to the corner of the venting unit 10 and can be at any position on venting unit 10 as desired for the application. Each actuator 92 of the plurality of actuators 91 may also extend through an actuator hole 66 (e.g., as shown in FIG. 9A-9B) located in the outer panel 60 and the inner panel 80. The actuator hole 66 may serve to support the actuator system 90 as it extends through the frame 12.
In some embodiments, the actuator system 90 is operable to transition the platen 50 from the closed position (e.g., as shown in FIGS. 3A-3B) to one or more open positions (e.g., as shown in FIGS. 5A-5C). In an open position, the actuator system 90 has moved the platen 50 outwardly from the venting unit 10 (e.g., outwardly toward the outdoor elements). The platen 50 may extend outwardly relative to the frame 12 and relative to the building structure 2. The position of an opening (e.g., as shown in FIGS. 5A-7B) in the one or more open positions may be selected to preferentially direct airflow through the airway 44 of the venting unit 10. The position (e.g., relative angulation and overall perimeter opening between the platen 50 and the remainder of the venting unit 10) may be selected due to weather patterns (e.g., wind direction) or inclement weather (e.g., rain, snow, sleet, and the like).
FIG. 4C is an exploded view of the venting unit 10 with the frame 12 and actuator system 90 removed, in accordance with some embodiments. The venting unit 10 includes a weather seal 42 that may seal the platen 50 and frame 12 when the venting unit 10 is in the closed position (e.g., as shown in FIGS. 3A-3B). The weather seal 42 is operable to create a weather-tight fit when the platen 50 is in the closed position such that that exterior elements (e.g., rain, snow, and the like) are prevented from entering the airway 44. The weather seal 42 may also create an air-tight seal that prevents the ingress of insects into the airway 44. The venting unit 10 further includes the outer panel 60, the filter 70, and the inner panel 80, where the airway 44 is defined through these elements and air flows in the airflow direction 46. Generally, the air flows in the airflow direction 46 from the outer panel 80 to the inner panel 80. The inner panel 80 may optionally include a cover 84.

The projected open position (FIGS. 5A-5B), the casement open position (FIGS. 6A-6B), and the awning open position (FIGS. 7A-7B) are all examples of the venting unit 10 in the open position.
In the projected open position of FIGS. 5A and 5B, all four of the actuators 92 in the plurality of actuators 91 are extended such that all four corners of the platen 50 are extended outwardly from the venting unit 10. The platen 50 may extend from venting unit 10 at a projected distance DP to define a projected opening OP. In some embodiments, as shown in FIG. 5B, the platen 50 may be extended the same projected distance DP from the frame 12 along a perimeter 52 of venting unit 10 such that the platen 50 is substantially parallel to the frame 12. The projected opening OP is defined such that air may be captured and directed to the airway 44 from any direction around the perimeter 52 of the platen 50. The projected distance DP may range from about 0.5 inches to about 1 inch, from about 1 inch to about 1.5 inches, from about 1.5 inches to about 2 inches, from about 2 inches to about 2.5 inches, from about 2.5 inches to about 3 inches, from about 3 inches to about 3.5 inches, from about 3.5 inches to about 4 inches, from about 4 inches to about 4.5 inches, from about 4.5 inches to about 5 inches, from about 5 inches to about 5.5 inches, from about 5.5 inches to about 6 inches, from about 6 inches to about 6.5 inches, from about 6.5 inches to about 7 inches, from about 7 inches to about 7.5 inches, from about 7.5 inches to about 8 inches.

The casement distance Dc may be measured between the platen 50 and the frame 12. The casement opening OC may be configured to capture and direct air to the airway 44 from select directions around the perimeter 52 of the platen 50. The select directions of the casement opening OC in the embodiment of FIGS. 6A-6B are along the perimeter 52 of the platen 50 that correspond to the second side frame member 20, and along part of the upper and lower frame members 14, 16 and the first side frame member 18 is closed. The reverse configuration where the first side frame member 18 is open and the second side frame member 20 is closed is also contemplated. As shown in FIG. 6B, the casement open position may also define a casement angle αc, defined along the upper and lower frame members 14, 16, that results in the casement opening OC along either the first side or second side frame members 18, 20. The casement angle αc may be measured between the platen 50 (e.g., along one or both of the upper and lower frame members 14, 16) and the frame 12. The casement angle αc may range from about greater than 0 degrees to about 45 degrees, or from about greater than 0 degrees to about 5 degrees, or from about 5 degrees to about 10 degrees, or from about 10 degrees to about 15 degrees, or from 15 degrees to about 20 degrees, or from about 20 degrees to about 25 degrees, or from about 25 degrees to about 30 degrees, or from about 30 degrees to about 35 degrees, or from about 35 degrees to about 40 degrees, or from about 40 degrees to about 45 degrees.
In the awning open position of FIGS. 7A-7B, two actuators 92 in the plurality of actuators 91 are extended such that two corners of the platen 50 are open and are extending outwardly from the venting unit 10.

As shown in FIG. 7B, the platen 50 may extend from venting unit 10 at an awning distance DA to define an awning opening OA. The awning distance DA may range from about 0.5 inches to about 1 inch, from about 1 inch to about 1.5 inches, from about 1.5 inches to about 2 inches, from about 2 inches to about 2.5 inches, from about 2.5 inches to about 3 inches, from about 3 inches to about 3.5 inches, from about 3.5 inches to about 4 inches, from about 4 inches to about 4.5 inches, from about 4.5 inches to about 5 inches, from about 5 inches to about 5.5 inches, from about 5.5 inches to about 6 inches, from about 6 inches to about 6.5 inches, from about 6.5 inches to about 7 inches, from about 7 inches to about 7.5 inches, from about 7.5 inches to about 8 inches. The awning distance DA may be measured between the platen 50 and the frame 12. The awning opening OA may be configured to capture and direct air to the airway 44 from select directions around the perimeter 52 of the platen 50. In FIGS. 7A-7B, the select directions are along the perimeter 52 of the platen 50 corresponding to the lower frame member 16, and along part of the first and second side frame members 18, 20 where the upper frame member 14 is closed. The reverse configuration where the upper frame member 14 is open and the lower frame member 16 is closed is also contemplated. As shown in FIG. 7A, the awning open position may also define an awning angle dc, defined along the first and second side frame members 18, 20 that results in the awning opening OA along either the upper or lower frame members 14, 16. The awning angle αc may be measured between the platen 50 (e.g., along one or both of the first and second side frame members 18, 20) and the frame 12. The awning angle αa may range from about 0 degrees to about 45 degrees, or from about 0 degrees to about 5 degrees, or from about 5 degrees to about 10 degrees, or from about 10 degrees to about 15 degrees, or from 15 degrees to about 20 degrees, or from about 20 degrees to about 25 degrees, or from about 25 degrees to about 30 degrees, or from about 30 degrees to about 35 degrees, or from about 35 degrees to about 40 degrees, or from about 40 degrees to about 45 degrees.
In some embodiments, the actuator system 90 is operable to angulate the platen 50 at a first angle (e.g., parallel to the frame 12, the casement angle αc, or the awning angle αa) to preferentially direct air through the airway 44 from a first direction (e.g., along the projected opening OP, the casement opening OC, or the awning opening OA, corresponding to the first angle) and to angulate the platen 50 at a second angle (e.g., parallel to the frame 12, the casement angle αc, or the awning angle αa) different than the first angle to preferentially direct air through the airway 44 from a second direction (e.g., along another of the projected opening OP, the casement opening OC, or the awning opening OA, corresponding to the second angle).
Similarly, in some embodiments, the actuator system 90 is operable to transition the platen 50 between a plurality of positions (e.g., the projected position of FIGS. 5A-5B, the casement position of FIGS. 6A-6B, or the awning position of FIGS. 7A-7B) to define a first opening (e.g., the projected opening OP, the casement opening OC, or the awning opening OA) into the venting unit 10 and a second opening (e.g., another of the projected opening OP, the casement opening OC, or the awning opening OA) into the venting unit 10, the first opening being angularly offset from the second opening. In some embodiments, the projected opening OP is parallel to the frame 12 such that the casement angle αc, or the awning angle αa are zero. In some embodiments, the first opening and the second opening are substantially perpendicular to each other (e.g., when the first opening and the second opening are the casement opening OC and the awning opening OA). In other embodiments, the first opening and the second opening are substantially parallel to each other (e.g., the projected opening OP and either one of the casement opening OC or the awning opening OA, the casement reverse opening positions OC, or the awning reverse opening configurations OA).
In some examples, to optimize the air reaching the airway 44, the actuator system 90 moves the platen 50 to the open position to create an air scoop. The air scoop can be preferentially created to match the wind direction. The air scoop can be defined at multiple angulated positions relative to the frame 12 (e.g., to accommodate different air directions, and speeds) and may correspond to the open position (e.g., along the projected opening OP, the casement opening OC, or the awning opening OA). The defined air scoop directs ambient air to the space between the platen 50 and the outer panel 60. The air is directed through the outer panel 60 and into the airway 44 by a tunneling effect. The tunneling effect uses the momentum of the air passing through the air scoop to direct, or push air through the airway 44 and out through the inner panel 80 such that mechanical air flow assistance (e.g., a fan) may not be needed for venting. In addition to air speed/air direction due to “winds”, thermal effects may also be accommodated (e.g., rising, heated air) to help direct air through the venting unit 10, using the air scoop to preferentially collect and direct air through the venting unit 10.
FIG. 8 is a front view of the platen 50 isolated from the venting unit 10, in accordance with some embodiments. In some embodiments, the platen 50 is operable to cover the airway 44 when in the closed position. The platen is generally operable to cover and seal the airway 44 when in the closed position. As described, the airway 44 may be sealed by the weather seal 42 coupled around a platen perimeter 52 and the frame 12 of the venting unit 10. As shown, the platen 50 is operable to move outwardly (e.g., outward toward the exterior elements) by the actuator system 90.
Further to FIG. 8, the platen 50 may be coupled to the frame 12 such that the platen 50 is resistant to being forced open by a force external to the platen 50. In some embodiments, the platen 50 may be latched or mechanically interlocked with the frame 12 to create a strong barrier such that removal of the platen 50 from the frame 12 is prevented. Further, in some embodiments, the platen 50 may be configured to extend outwardly at a maximum distance of between about 0.5 inches to about 8 inches from the venting unit 10. These features may increase security as compared to an open fenestration unit and prevent forced entry through the venting unit 10.
Further to FIG. 8, in some embodiments, the venting unit 10 further includes a solar panel 54 coupled adjacent to the platen 50. The solar panel 54 may be sized such that it covers an entirety of the platen 50 or may be sized to cover less than an entirety of the platen 50. The solar panel 54 may be operable to provide power to a battery pack (e.g., a battery pack to drive the actuator system 90) or may provide power for the building structure 2, for example. In some embodiments, the actuator system 90 is operable to transition the solar panel 54 between a first solar panel position (e.g., one of the projecting, casement, or awning positions) and a second solar panel position (e.g., another one of the projecting, casement, or awning positions) to preferentially capture solar energy, wherein the first solar panel position and the second solar panel position are angularly offset. In this regard, the actuator system 90 may be driven to move the platen 50 to one of the projecting, casement, or awning positions such that the solar panel 54 is preferentially facing the direction of sunlight.
FIGS. 9A and 9B are an isometric view and a front view, respectively, of the outer panel 60 isolated from the venting unit 10, in accordance with some embodiments. In this embodiment, the outer panel 60 includes a louvered panel, and the louvered panel includes a plurality of slats 62. The plurality of slats 62 may extend outwardly from the louvered panel at a fixed angle such that a gap 64 is created between each slat in the plurality of slats 62. Each gap may be configured such that air is able to pass through the plurality of slats 62 and pass though the outer panel 60 to move through the airway 44. The fixed angle of the plurality of slats 62 may be set such that the louvered panel is at one fixed angle relative to the airway 44 and relative to the airflow direction 46. In other embodiments, the plurality of slats 62 may have a variable angle such that the angle of plurality of slats 62 can be changed affect the amount of air entering the airway 44 through the outer panel 60 (e.g., by increasing or decreasing the gap 64). In some embodiments, the gap 64 may be sized such that insect entry into the airway 44 is prevented. In other embodiments, the louvered panel may be covered with a screen 63 (e.g., an insect screen) to prevent the ingress of bugs through the panel.
Further to FIGS. 9A-9B, the outer panel 60 may include a space 68 around a perimeter of the outer panel 60. The space 68 may be filled with a seal (e.g., a weather seal or an air seal) to reduce air bleed around the outer panel 60. The outer panel 60 may also include a plurality of holes 66 for the actuators 92 in the actuator system 90 to fit through as the actuators 92 extend through the frame 12. The plurality of holes 66 in the outer panel 60 may be in line with the plurality of holes 66 in the inner panel 80.
In some embodiments, the outer panel 60 may be latched for mechanically interlocked with the frame 12 to create a strong barrier and prevent removal of the outer panel 60 from the frame 12. Similar to the platen 50, this feature may increase security and prevent forced entry through the venting unit 10.
FIGS. 10A and 10B are front views of the filter 70 isolated from the venting unit 10, in accordance with some embodiments. The filter 70 may trap and remove particulates, such as allergens, from the air in the airway 44 prior to the air exiting the interior side 5 and entering the building structure 2. The filter 70 may include a pleated filter. The filter may include, but is not limited to, a filter with a Minimum Efficiency Reporting Value (MERV) between 1-16 or a high efficiency particulate air (HEPA) filter. The filter 70 may be replaceable. The filter 70 may also include a filter cartridge 72. The HEPA filter cartridge may include, but is not limited to, a about 2-inch-thick tri-pleated HEPA cartridge. However, the filter 70 thickness or filter cartridge 72 rating can vary depending on the application. In some embodiments, the venting unit 10 further includes a fan 74, or a plurality of fans 74, adjacent to the filter 70. The fan 74 may be configured to pull air through the filter 70. The fan 74, or plurality of fans 74, may be utilized with filters 70 of a higher MERV rating or with HEPA filters.
FIGS. 11A and 11B are an isometric view and a front view, respectively, of the inner panel 80 isolated from the venting unit 10, in accordance with some embodiments. The inner panel 80 may include a screen 82 to allow air to flow out of the airway 44 to the interior side 5 and exit the airway 44 to the interior of the building structure 2. The screen 82 may allow an indoor environment (e.g., the inside of a home) to receive filtered air from the venting unit 10. The screen 82 may include a cover 84. The cover 84 may include, but is not limited to, speaker grill fabric. The cover 84 may lead to improved aesthetics of the venting unit 10 as it faces the interior of the building structure 2.
FIGS. 12A and 12B are a side view and a front view of an actuator 92 in the actuator system 90 isolated from the venting unit 10, in accordance with some embodiments. The actuator 92 may include an inner panel side 94 and a platen side 96. The inner panel side 94 and the platen side 96 may be connected by a frame extension portion 98. The inner panel side 94 is operable to engage with the inner panel 80 and may be held in place by a tightener 95 such that the inner panel side 94 may be operable to tighten or seal against the inner panel 80 (e.g., as shown in FIGS. 9A-9B). The platen side 96 is operable to engage with the platen 50 and extend the platen 50 outwardly from the frame 12. The frame extension portion 98 may fit through the holes for actuators 66 and extend through the frame 12, or along the airway 44 (e.g., as shown in FIGS. 4A and 4B).
In some embodiments, each of the actuators 92 in the actuator system 90 may be mechanically driven. In this embodiment, each of the actuators 92 may include, but are not limited to, a type of 4-bar linkage system (e.g., scissors), a gear rack and pinion set, a sliding action leadscrew, or a slider-crank mechanism. In some embodiments, the mechanically driven actuators in the plurality of actuators 91 may be driven a mechanical driver, which may include, but it not limited to, at least one of a crank, a button, or a slide. In some embodiments, the mechanical driver is located on the interior of the building structure 2 and is driven by a user.
In other embodiments, each of the actuators 92 in the plurality of actuators 91 may be powered actuators. In this embodiment, each of the actuators 92 may include, but is not limited to, an electric linear motor, a voice-coil motor, a linear induction motor, or a brushless electric motor (e.g., a stepper motor).
In further embodiments, the platen 50 may include a hinge along at least one edge of the perimeter 52 (e.g., along at least one of the upper frame member 14, the lower frame member 16, the first side frame member 18, and/or the second side frame member 20). Opposite of the hinge, at least one actuator 92 in the plurality of actuators 91 may be operable to rotate the platen 50 outwardly about the hinge. For example, in the casement open position of FIGS. 6A-6B, the hinge may be located along the first side frame member 18 and one or more actuators 92 along the second side frame member 20 may rotate the platen 50 about the hinge. Similarly, in the awning opening position of FIGS. 7A-7B, the hinge may be located along the upper frame member 14 and one or more actuators along the lower frame member 16 may rotate the platen 50 about the hinge.
In some embodiments, the venting unit 10 may further include a control system 100. The control system 100 may be in communication with actuator system 90 such that the control system 100 is operable to drive the actuator system 90. The control system 100 may include algorithms for adjusting the position of the platen 50. In some embodiments, the control system 100 may be integrated within a home automation system or a home security system 102. In this embodiment, a user of the home automation system may input user input 108 (e.g., settings or preferences) for the movement of the platen 50 (e.g., time of day or position for the platen 50 opening) where the input settings or preferences are communicated to the control system 100 and drive the actuator system 90 to open the platen 50. The platen 50 may be selectively transitioned to the open position (e.g., as shown in FIGS. 5A-5C) as in a configuration determined to be preferential (e.g., in the direction of wind to scoop, or direct wind through the venting unit 10).
In some embodiments, the venting unit 10 may further include a sensor 104 in communication with the control system 100. The sensor 104 may be configured to receive weather information 106 (e.g., local wind speed, wind direction, air temperature, presence of rain, sleet or snow, and the like) and send the weather information 106 to the control system 100. The weather information 106 may account for pre-determined, expected, or actual weather events. The weather information 106 may be used to determine which position (e.g., the closed position of FIG. 3A, the projected position of FIG. 5A, the casement position of FIG. 5B, or the awning position of FIG. 5C) the platen 50 should be moved to. For example, the platen 50 may be moved to a closed position or adjusted to close off a gap at the upper edge of the platen 50 to act as a rain screen, if rain is detected by the sensor 104. And, the platen 50 can be moved or transitioned to the projected configuration (FIG. 5A) to preferentially capture wind. The sensor 104 may be located proximate the platen 50 or within the frame 12 of the venting unit 10. The sensor 104 may be configured to receive weather information from local weather reports.
FIG. 13 is a diagram of the building structure 2 with a plurality of venting units 10 installed, in accordance with some embodiments. One or more of the venting units 10 may be maintained within a fenestration unit, such as the fenestration unit 30. In other embodiments, one or more of the venting units 10 may be installed directly into the building wall 4 as a separate unit from any fenestration unit, such as the fenestration unit 30.
The plurality of venting units 10 may be installed in the building structure 2 (e.g., a house) to preferentially direct airflow through the interior of the building structure 2. The building structure 2 may include a cold side 120 (e.g., a side in the shade) and a hot side 130 (e.g., a side that receives direct sunlight). The cold side 120 and the hot side 130 are defined as cold and hot relative to each other. A venting unit 10 may be placed on both the cold side 120 and the hot side 130 of the building structure. In some embodiments, the venting unit 10 is placed on the lower side (e.g., the lower frame assembly member 36) of fenestration unit 30 on the cold side 120 and the venting unit 10 is placed on the upper side (e.g., the upper frame assembly member 34) of the fenestration unit 30 on the hot side 130. In this configuration, when the venting units 10 on the cold side 120 and the hot side 130 are open, natural ventilation is encouraged through the building structure 2. Natural cross ventilation, from wind or other natural forces, can be encouraged through the building structure 2 for cooling. Cool airflow 122 can enter the building structure 2 and flow at an interior flow direction 124 through the interior of the building structure 2. In other embodiments, the venting unit 10 may utilize mechanical ventilation and the fan 74 may encourage cool airflow 122 to enter the building structure 2. In either embodiment, natural stack ventilation (e.g., thermal buoyancy) may also help to keep the building structure 2 cool after the cool airflow 122 enters the building structure 2. As the cool airflow 122 moves through the interior of building structure 2, the cool airflow 122 may meet with a warm airflow 126. Due to the higher density of the cool airflow 122 and the tendency for warm air to rise in the presence of cool air, the warm airflow 126 may rises toward the top of the building structure 2. Then, the warm airflow 126 is able to exit the building structure 2 as warm air 128 through the venting unit 10 and/or the fenestration unit 30 on the hot side 130. This configuration allows the building structure 2 to vent warm air 128 to the exterior of the building structure 2 such that the building structure 2 cools down through natural cross ventilation and natural stack ventilation. This natural ventilation of venting unit 10 may have a higher air flow than a trickle vent system and could lead to increased home energy savings. The natural ventilation system of venting unit 10 could also integrate with house fans, or other building system fans, to improve air movement throughout the home, such that a hybrid ventilation system is employed in the building structure 2.
Various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the present invention. For example, while the embodiments described above refer to particular features, the scope of the invention also includes embodiments having different combinations of features and embodiments that do not include all of the above-described features.
